DataTable property causes the error "The JSON property 'Item' is defined multiple times on type 'System.ComponentModel.ComponentCollection" #3927

This occurs when there is a property of type DataTable on a response or request object. Similar to #755

I am running into a similar issue when generating openapi from webapi (this project is not dotnet core) and I have a DataTable on my response object.

@RicoSuter Is there any known workaround?
